POWER switch
Use the POWER switch to turn on the mixing console. The POWER switch
should always be in the "Off" position when you are about to connect your unit
to the mains.
To disconnect the unit from the mains, pull out the main cord plug.
When installing the product, ensure that the plug is easily accessible. If mounting
in a rack, ensure that the mains can be easily disconnected by a plug pull or by an
all-pole disconnect switch on or near the rack.
◊
Attention: The POWER switch does not fully disconnect the unit from
the mains. Unplug the power cord completely when the unit is not used
for prolonged periods of time.
PHANTOM switch
The PHANTOM switch activates the phantom power (necessary to operate
condenser microphones) on the XLR sockets of the mono channels. The red +48 V
LED illuminates when phantom power is on. As a rule, dynamic microphones can
still be used with phantom power, provided that they are wired in a balanced
configuration. In case of doubt, contact the microphone manufacturer!
◊
Connect microphones before you switch on the phantom power supply.
Please do not connect microphones to the mixer (or the stagebox/
wallbox) while the phantom power supply is switched on. In addition,
the monitor/PA loud-speakers should be muted before you activate the
phantom power supply. After switching on, wait approx. one minute to
allow for system stabilization.
◊ Caution! Please also note the information given in chapter 6.2.1
"Audio connections".
SERIAL NUMBER
Please note the important information on the serial number given in
chapter 1.3.3.

6. Installation

6.1 Rack mounting

The packaging of your mixing console contains two 19" rack mounts for
installation on the side panels of the console.
Before you can attach the rack mounts to the mixing console, you need to remove
the screws holding the left and right side panels. Then, use these screws to
fasten the two rack mounts, each specifically to one side. With the rack mounts
installed, you can mount the mixing console in a commercially available 19" rack.
Be sure to allow for proper air flow around the unit, and do not place the mixing
console close to radiators or power amps, so as to avoid overheating.
◊ Only use the screws holding the mixing console side panels to fasten
the 19" rack mounts.

6.2 Cable connections

You will need a large number of cables for the various connections of the console.
The illustrations below show the wiring of these cables. Be sure to use only
high-grade cables.

6.2.1 Audio connections
Please use commercial RCA cables to wire the 2-TRACK inputs and outputs.
You can, of course, also connect unbalanced devices to the balanced input/
outputs. Use either mono plugs, or use stereo plugs to link the ring and shaft
(or pins 1 & 3 in the case of XLR connectors).

power supply.
